TORONTO, ONTARIO--(Marketwire - Jan. 7, 2013) - Greencastle Resources Ltd. (TSX VENTURE:VGN) ("Greencastle" or the "Company") is pleased to provide an update on the activities of both Greencastle and its subsidiary Deveron Resources Ltd. (TSX VENTURE:DVR) ("Deveron").

The Nechako property, covering approximately 13,000 hectares (28 claims), is located approximately 100 kilometres southwest of Vanderhoof, central British Columbia, in the developing Blackwater gold camp, where New Gold Inc. has recently delineated an open-pit resource of over 10 million ounces of gold.

Rainbow Resources Inc. ("Rainbow") has completed six reverse-circulation drill holes at Greencastle's Jewel Ridge property as well as numerous rock samples that were collected over a wide area as reported by Rainbow on January 2, 2013. Assay results for Jewel Ridge are pending. Rainbow can earn a 60% interest in the Jewel Ridge property by paying Greencastle $250,000 cash ($25,000 paid), issuing 1.5 million shares of Rainbow (250,000 issued) and spending $4.5-million over four years. Upon earning a 60% interest in the property, Rainbow can elect to increase its interest to 75% by advancing the property to the stage of a bankable feasibility study.

Jewel Ridge is located on the south end of Nevada's prolific Battle Mountain - Eureka Trend, along strike and contiguous to the north with Barrick Gold's two-million ounce Archimedes / Ruby Hill mine.
